<span>The answer is\ compound, B. A compound is a particle made of molecules from various components. All mixes are particles, however not all atoms are mixes. Hydrogen gas (H2) is an atom, however not a compound since it is made of just a single component.</span>
Answer:
21.6 grams
Explanation:
First we <u>convert 10 g of N₂ into moles</u>, using its <em>molar mass</em>:
- 10 g ÷ 28 g/mol = 0.36 mol N₂
Then we <u>convert 0.36 moles of N₂ into moles of NO</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 0.36 mol N₂ *
= 0.72 mol NO
Finally we <u>convert 0.72 NO moles into grams</u>, using its <em>molar mass</em>:
- 0.72 mol NO * 30 g/mol = 21.6 g
Answer:
Theoretically you could be totally unrelated to your sister or share the exact same DNA as your brother. But because we are talking about so much DNA and so many different possible combinations, the percentage usually comes out to about 50%. Think about it like flipping a coin.
Explanation:
Answer:
134.8 seconds is the half-life (in seconds) of the reaction for the initial
concentration
Explanation:
Half life for second order kinetics is given by:

Integrated rate law for second order kinetics is given by:

= half life
k = rate constant
= initial concentration
a = Final concentration of reactant after time t
We have :

Initial concentration of ![C_2F_4=[a_o]=\frac{0.438 mol}{2.42 L}=0.1810 mol/L](https://tex.z-dn.net/?f=C_2F_4%3D%5Ba_o%5D%3D%5Cfrac%7B0.438%20mol%7D%7B2.42%20L%7D%3D0.1810%20mol%2FL)
Rate constant = k = 



134.8 seconds is the half-life (in seconds) of the reaction for the initial
concentration
